Angular ng 新返回包安装失败错误 - compiler.umd.js 丢失

Question

I am trying to learn Angular and am following an online tutorial. However, I can't seem to get past creating a new project with ng new. I am running node v10.16.0 and npm 6.9.0 on Windows 7. I get the following error in the log:

15188 verbose exit [ -4048, true ]

I followed the path specified above and the lib folders are empty. I tried reinstalling node, reinstalling angular, clearing the cache with --force, running as administrator, restarting. Nothing is helping.

Please note that I am a complete noob at this and am just trying to learn the framework, which right now seems impossible to work with.

I expect the packages to install and the project to be created without issues.

Answer 1

For some reasons when angular/cli (ng) run npm install by itself, it have problem with packages writing, so you can run

ng new yourProject --skipInstall=true

so angular/cli will not install any node packages and then run

npm install --force

to install it by yourself

Answer 2

I've faced like this issue and the solution was:

1. Go to Edit the system environment variables .
2. Under User variables for User ==> Path , Make sure C:\\Users\\user\\AppData\\Roaming\\npm its above all, and make sure you are add current user directory.

Note : If you don't have current user directory you have to create it.

3.Under System variables ==> Path , Make sure * C:\\Program Files\\nodejs* its above all.

4. Open Command Prompt as user ==> npm cache clean --force .
5. npm install -g npm@lates t.
6. ng new yourApp .
7. ng serve --open .

Answer 3

are you working offline? you need to be online, so that npm can download the dependencies for the project.
